Is there a bug with firebase clear tag?

I have added one more level within the “tag” and I think I know where the problem comes from

this are my blocks

and my database

But instead of deleting the tag “Jugadores” delete the last part of the bucket that you select

Before, the “tag” that I used was “F95GM6M7A” and it deleted all the content, adding one more level instead of deleting the tag I request, it deletes one before the order. I do not know if I explained well

There is the result after click the botton
